If you are using a Bootstrap plugin

This is avery short tutorial, but if you plan to use a plugin that loads the Bootstrap CSS styles, you may want to disable the theme’s own Bootstrap CSS so that you don’t have duplicate stylesheets loading. Although the theme has it’s own Bootstrap styles, they are limited to the grid layout and some form styling. Disabling the theme’s own styles will affect the grid layout due to specific sizing I applied to this theme.

NOTE This theme loads the Bootstrap CSS by default.

Disable Bootstrap Styles

Go to Appearance >> Customize >> Site Options

Look for the Bootstrap setting and uncheck the box to disable the built-in styles
